I have a stock H23 that I am rebuilding because it has rod knock. I cannot decide whether to go N/A or turbo. This will be a daily driver for a while (year or so maybe longer) and possibly a track car one day. I know turbo cars are always faster, but N/A builds are awesome and good for the street too.
If I were to go N/A, I would get forged rods, high compression pistons (not sure how high, but one day the motor will see nitrous), better cylinder sleeves, and an H22 head. How much power would that make?
If I went turbo, I would get forged rods, lower compression pistons, better cylinder sleeves, and the DSM junkyard turbo kit. How much power could this make? One day I would upgrade the turbo system, like a better manifold, bigger turbo, etc.
I'm leaning more towards the N/A setup honestly. Turbo kits can be a lot of headaches. I am mostly into straight line performance and want to see what kind of quarter mile times I can pull from a streetable N/A h-series motor. I also will probably go with nitrous to run here and there as well.
How much hp would an H23 make with forged rods, higher compression pistons (maybe 11:1?), and an H22 head? When you swap the head to an H22, does this make the power output similar to an H22, or are there other differences?
I've never seen an all out N/A prelude do better than low 13's. You can do that without the crazy build, just with nitrous. I've seen so many builds with varying hp output, that you really can't paper dyno things. It should get better output with a nicer tq curve.

Yeah I think N/A will be good for being a dd, and I can get nitrous for the track. A lot of weight will be taken out (everything behind the front seats, power steering, possibly a/c). I am at first going to put in new forged rods and h.c. pistons b/c they are needed for the rebuild. Eventually I'll come back in with a Vtec head, cams, and full exhaust, topped with nitrous (100 shot? not sure how much these motors can hold w/ forged internals), and see what I can do with some slicks on drag wheels.
Well Jared, I see it was an easy decision for you! That looks like the way I'm going. If you don't mind me asking, Jared, what mods do you have to get that 13.7? How big of a nitrous shot can an H23 run with forged rods and pistons and strong sleeves without making the motor on borrowed time?

His sig says he's running a 100 shot.

hmm...I have had rod knock on my F22B for a few years now....I wonder how much longer it will last. I should rebuild and supercharge it...
I personally would go N/A
Lol, thats one way to look at it! The motor I have has not really been ran in a year or so, and the owner said the last time it did run, it had some pretty bad noises coming from the internals, what he was PRETTY SURE was rod knock. I may tear this motor apart to find even worse damage, or even perhaps not bad damage at all (doubt it). No matter what though, since the motor will be apart, new rods and pistons will go in.
I have also been reading that the cylinder sleeves in these motors are junk. True? Also, what do you guys recommend replacing them with?
I have also heard from many that the stock crank on Hondas are very durable. What kind of power can these things handle?
Well N/A is the way I'm going. I'm looking for suggestions on which rods, pistons, and sleeves to get. What would you guys do? I'm looking for cost effective performance.
I'm also still deciding on what C/R I should go for. What is a good compression for an N/A H-series motor? What is a good compression for an N/A H-series that will still accept nitrous?
